RADIATOR GAP.

Application filed June 23, 1927. Serial No. 200,861.

have the ordinary hinge movement with respect thereto but will be permitted a limited lateral movement on the hinge so as to efi'ect a lockingbetween the inter-engaging porlo tions of the stationary portion and the cap cover.

It is a further object to provide a sealing member of a resilient water-absorbing material which is resistant to acids, alkalis and 1 heat, and so confine and arrange such sealing member that this absorption of moisture and its expansion will be so confined and directed in the proper direction that its properties will be taken advantage of and so directed as to improve the sealing effect the longer the material is used.

It is my .further object to provide specificallya vulcanized fiber sealing ring, which has the proper properties and resiliency, re-

sistance to corrosives and heat not found in rubber and other similar materials, for use as a sealing ring and to locate it in an open top metal channel so that it can only expand upwardly to improve the sealing effect between the cap cover and body.

Referring to the drawings:

Figure 1. is a section on the line 11"of Figure 2; 1

Figure 2 is a front elevation partially broken away to show the locking arrangement; I Figure Figure 1; 4

Figure 4fis a topplan view with the cover cap in raised position; I

Figure 5 is a front elevation with the cover 3 is a section on the line of cap in elevated position so as to disclosethe interior arrangement ef the cover cap. I Referring to the drawings in detail,'1 is a 'stat-ionarybody portion internally threaded at 2 for attachment to the radiator. This body is provided with" an internally extending flange 3 surrounding the interior passageway 4. Such flange is provided with a.shoul- .der 5 which forms one wall of a groove 6', the.

other. wall of which is formed by the shoulder 7 of the upper portionof the body 1.. In this groove is located a fiber ring 8. The ring is confined on three sides but is free on its upper 65 side toexpand upwardly.

' It will be understood that Letters Patent, is

.g/ Such a fiber ring of vulcanized fiber absorbs moisture, is resistant to heat, alkalis and acids, such as are commonly found in radiator COIlSlZILlC'tlQIlS. and operation, but

when so heated and moistened has a tendency to expand. By confining a ring in a groove and permitting it only to expand upwardly 'theresult isthat the sealing effect of this ring is improved and the more it expands the better the seal. The resilient diaphragm 9 engages with 'this sealing ring and accommodates itself to the height of the ring. Such resilient diaphragm is carried on the depending annular ring 10 and a central sleeve 11 depending from the cap cover 12. The stud 13 serves to retain the parts in operative position.

This cap cover 12 is provided with a depend ing hinge lugl 4. This lug'has an aperture therethrough designated 15 which is broader than it is deep so that the capcover may move laterally with respect to the stationary portion 1. The attachment of the cap cover with respect to the stationary portion is through the. hinge pin 16- carried in the adjacent ears or space ends of the rin 17 formed as an annulus on the upper edge 0 the body 1. t The body 1 is attached to the radias tor through the set screw 18 in the usual manner.

-The ring :17 has anupwardly and out- "wardly projecting hook member 19 engaging.

with an inwardly'projecting hook member 20 carried on the cap member. These two hooks are adapted to interlock or unlock by the lateral movement of the cap cover with respect to the stationarybqdy 1, which lateral movement is provided for by the elon' gated slot 15 which is elongated and widened in a horizontal plane to permit of this lateral movement'and vertical. movement of the cap cover about the point of hinging of the cap cover to the statlonary bodyIportion 1. a

desire to comprehend within my invention such modifications asrna be necessary to ada ted it to vay P rying conditions and uses. Having thus fully described my i. ,lention, what I claim as new and desire to secure by 10 1; In a radiator cap "a stationary portion, a cap cover adapted to he hinged thereto, and means of connecting said cap cover and stationary portion so as to'prov1de both for vertical hingedmovement of the cover and lat- 110 eral movement with respect to the stationary portion.

2. In a radiator cap, an annular body portion, a "cap cover adapted to be hinged thereto, a hinge pin for connecting the cap cover to the body member, said parts being so arranged as to permit of lateral movement of the cap cover with respect to the hinge pin and rotating movement with respect thereto.

3. In combination in a radiator cap, of an annular stationary portion, an interlocking laterally movable pivoted cap member p ivoted thereon, and a hinge connection between the stationary portion and the cap member constructed to permit horizontal and vertical swinging motion about a single point.

4. In combination in a radiator cap, of an annular stationary member havmg a portion of one side cut away, a cap having a de ending hinge member extending into sa-i .cut-

away portion, said depending member having a lateral elongated slot therein, a hinge pin in said stationary member and passing through said elongated slot to form a loose connection and interlocking means on said cap cover and stationary member for locking the two together by lateral movement of one with respect to the other.

5. In combination in a radiator cap, of an annular stationary member having a portion of one side cut away, a cap covervhaving a de pending hinge" member extending into said cutaway portion, said depending member having a laterally elongated slot therein, a hinge pin passing through said stationary member and said elongated slot to form a loose connection and interlocking means on said cap cover and stationary member =or locking the two together by lateral movement of one with respect to the other, said a cap cover adapted to be hinged thereto, and

means of connecting said cap cover and stationary portion so as to provide both for vertical hinged movement and lateral-movement with respect of one to the other about a single point, and means carried by the stationary member to provide for a smooth and close fit between the stationary member and the cap cover when the cap cover is in closed position. H

7. In a radiator cap, an annular body portion,4a cap cover adapted to be hinged thereto, a hinge pin for connecting the cap cover and the body member to one another, said parts being so. arranged as to permit of lateral movement of the cap cover with respect to the hinge pin and vertical rotating move.- ment with respect thereto, a fiber ring carried by said stationary member and engaged by said cap cover to form a smooth and close connection therebetween.

In testimony whereof, I aflix my signature.
